FYI folks, for those of you who are experiencing oddities with 2.1.0 and updating Extras that have new versions (specifically ones whose new versions are 2.1+ only), there is a bug in 2.1.0 that is not sending the MODX version correctly, creating this issue.
The issue occurs when your grid shows you having an update available for an Extra (such as Batcher), but clicking Yes and updating says "Your package is already up-to-date".
A simple fix can be applied to remedy the issue (no need to change the changelog file):

Thanks guys, and we’ll have 2.1.1 out in the next few days to address these (and other) issues.
